Merge branch 'rcu/next' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into core/rcu
Pull RCU updates from Paul E. McKenney:
- Streamline RCU's use of per-CPU variables, shifting from "cpu"
arguments to functions to "this_"-style per-CPU variable accessors.
- Signal-handling RCU updates.
- Real-time updates.
- Torture-test updates.
- Miscellaneous fixes.
- Documentation updates.
